REVOLVING-CYLINDER INTERNAL-COMBUSTION ENGINE. I

Application m June 15, 1911. Serial in. 033,331.

Specification of Letters Patent.

Patented Dec. 17, 1912.

To all whom it may concern:

Be it known that I, 01m BENJAMIN Rnonur, a subject of the King of England, residing at Canton, Cardiff, county of Glamorgan, England, have invented certain new and useful Improvements in Revolving-Cylinder Internal Combustion Engines, of which the following is a specification.- 4 This invention is for improvements in or relating to internal combustion engines 0 the type wherein the cylinders are disposed radially to the crank-shaft and rotate relatively thereto and preferably the crankshaft also rotates in the reverse direction to the cylinders. I

Another feature of this invention consists in the employmentof a drum-shaped crankchamber that has cylinders arranged radially around the cylindrical portion of the crank case, every alternate cylinder being staggered so that a space is left between any first and third cylinder to accommodate induction pipes, tappet rods, and associated parts. i p

The invention f urther-relates to construetional details of the rotating crankcase and associated parts, the novel features of which details are set forth in the claims.

In the accompanyi g drawing the cylin ders A are radially disposed around the periphery of a drum-shapedcrank-chamber B and alternate linders are staggered so that is le between the first and third cylinders a, a on the left of the figure, and a space B is left between cylinders a a on the right of the figure. In the space B the two induction pipes C, 1 of-two adjacent cylinders are accommodated and in the space B the 'valveoperating mechanisms D, D are accommodated. From the above description it will be seen that half of the cyla space E inders lie in one plane and the other half in another plane, those in one plane being situated opposite'the spaces; between those in the other plane.

The crank-chamber B has one end wall hollow so that a chamber B is formed within the wall and communication is made between this and the induction pipes of the cylinders, by a hollow channel m part of the circumferential wall. The end wall referred to carries a hollow trunnion and surrounding this is a hollow ring F. The ring F is stationary and constitutes an annular chamber which communicates with a the first and third of two adjacent cylinders tion of this engine is 'of the parts carburetor F The ring has ports F formed in it on that side which is toward the end wall of the crank-chamber and the crank-chamber has in this wall correspondingports B. .The ring F is maintained against the wall of the crank-chamber by a spring or other means not shown and the' explosive fluid passes readily from it to the chamber B in the wall-of the crank-case by the ports F and B. the crank-ease B the end wall low trunnion E and within the trunnions E, E though not necessarily in direct contact therewith, lies the crank-shaft G.

The crank-case is supportedon the lefthand side of the figure by a ball-bearing H though the cupped end J of a shaft J is introduced between this hearing and trunnion E which extends beyond the hear ing and is made a tight fitwithin the cupped end J The other side of the crank-case B is adapted to be supported in a similar man ner.-

The hollow end wall of the left-hand portion of the crank-case as shown in the drawing, is conveniently cast in one cylinder carrying portion.

The cup-shaped end J provided with a lubricating conduit L and ring U, the end of the shaft G being bored at G to conduct-"the lubricantto the crank nearest that endof the shaft. noted, of course, that the opposite end of the shaft G is adapted to be lubricated inv a similar manner. f

It will be understood that the ball-bearings H, referred to as carrying case by means of the partsconnec'ted therewith, are themselves carried by any suitable On the other side of.

B has aholthe ' It will be the crankstationary support which it is not necessary to show in the drawing.

An important feature in the constructhat the arrangement described above enables the valve mechanism and the magneto mechanism each to be operated in proper time relation to the shaft and cylinder without interposition of any fixed member, that is to say that all the gear which effects the proper relative movement of these parts is carried-by the moving parts of the engine; thus the whole engine and gear can be removed bodily out.

It will be appreciated that the hollow end wall in the crank-chamber and the hollow channel in the circumferential wall of the same is a convenient method of conveying the explosive fluid from the ring F to the A drum-shaped crank cham having a hollow end wall however, is not new in itself.

What I claim as my invention to secure by Letters Patent is In an internal combustion engine, the combination of a casing; a plurality of cylinders mounted on and disposed radially of the casing, said cylinders arranged in staggered relation to provide spaces between alternate cylinders; and fuel feeding, and controlling means therefor mounted within said spaces, substantially as described.
